VANNER.

Specification of Letters Patent.

Patented June 8, 1909.

l To all whom it may concern.'

Be it known that I, GRANT B. SHLPLEY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful. Improvements in Vanners, of which the following is a specication.

This invention relates to vanners of the type which provides an endless belt Vfor receiving the ores or metals and water, said belt being adapted to be driven continuously while at the same time it receives a side shake in order that the ores or metalsmay be separated .from the worthless rock.

In the drawings which accompany this specification and form a part thereof, and on which the same reference characters are used to designate the same elements whereever they may appear in each of the several figures of the drawingsVfFigure "1 repreents a plan view of a vanner of the type described embodying this invention. Fig. 2 is a side elevation of the front end thereof, parts being shown in section. Fig. 3 is an end elevation of the front end thereof, parts being shown in section. Fig. 4 isa plan view of the speed changing device taken on the line n n, Fig. 2, parts being shown in section. Fig. 5 is a broken Vperspective view of the pipe-shaft and attached arm and bell crank lever.

The numeral 1 designates standards from which the belt frame is supported, there being four of these, two being located at each end of the machine.

Extending across the machine and engaged with the tops of the standards 1 at each end of the machine are braces 2, and extending lengthwise of the machine and connecting the standards 1 on each side of the machine are the bracing rods or bolts 3.

The numeral 4 designates supporting blocks which are adapted to be supported by the brace rods 2, and from which the belt frame is supported by the turnbuckles 5, said turnbuckles being pivoted to said supporting blocks by the pins 6 and to lugs on the table frame by the pins 7, each turnbuckle being preferably composed of two threaded portions 8 and 9, and an intermediate, threaded sleeve portion 10 within which the members 8 and 9 are screwed. The supporting Vblocks 4 are slidable upon the brace bars 2, being adapted to be moved back and forth thereon by means of screws 11 with which they are in screw threaded engagement, said screws being rmly secured to lugs 12 which are fastened immovably to the standards 1.

The belt frame 13 is composed of channel bars 14 which run the full length of the machine and are secured together by the pipes 141 and bolts 142 passed therethrough, and to which channel bars are secured thebelt rollers 15 and 16 and the usualintermediate supporting rolls 17. Secured to said channel bars 13 are the depending frames 18 to which is journaled the lower roll 19.

The numeral 2O designates a roll movably supported from the channel bars 13 by pivots 21 and depending arms 22, said depending arms 22 being provided with proj ections 23 extended on opposite sides thereof and in the general direction of the length of the belt table, said projections being provided with screw-threaded apertures within which are received screws 24 which are adapted to contact with the channel iron 14, thereby swinging the roll 20 nearer to, or farther from, channel irons 14, whereby the tension of the ore carrying belt 30 may be increased or decreased.

The numeral designates the usual countershaft with which these vanners are provided. In this case the countershaft is placed across the machine instead of lengthwise thereof, as inthe case of installing bat teries of vanners it is found to be more convenient to place them with their rear ends disposed near the walls of the mill, whereby one or more rows of vanners may be operated from a single line of main shafting without having recourse to twisted or crossed belts. This countershaft 40 is secured in a suitable bearing 41 on one side of the machine, while on the other side of the machine it is secured within a box 42, which is so arranged as to provide two bearings for said shaft, one at each side of said box, as clearly shown at 43 and 44 of Fig. 4. This countershaft 40 also carries the Hy wheel 45, the fast pulley 46, and the loose pulley 47, which latter are held on the shaft by the collar 470.

The box 42 is secured to the bracing rod 3 at one side of the machine and is also supported by the countershaft 40, this box being provided with a top 45 which is removable from the lower part of the box, being ordinarily secured to said lower part by bolts passed through apertured lugs, or by similar fastening means.

Upon the shaft l() and located within the box 12 is the cone pulley 4:8, and within the same box is a reversely turned cone pulley 19 secured to a shaft 50 which is journaled in bearings 51 and at each side ol' the box, and secured to shaft 50 is the spiral gear 53.

rQlhe numeral 5st designates a belt encircling the two cone pulleys 4S and A19, and for tightening and shitting this belt along the cones, the following arrangement ot apparatus is provided. rlhe numeral 60 designates a rod, circular in cross section, upon which is mounted the pulley 61 which is provided with shoulders 62 which engage with the sides of the belt 5d to shift said belt along said cone pulleys. r)The rod GO is supported by two arms 63 and 6st located near each side of the box, and these arms G3 and Ga are provided with hubs through which passesa rod 65 provided with a screw threaded portion G6. rEhe hub ot the arm 63 passes outwardly through a journal bearing G7 formed in the side of the box, and on the exterior portion, which is screw-threaded, is provided a lock nut G8 provided with a handle 69, and said hub is also provided with a handle iirmly secured thereto, as by the set screw 71. rThe rod 65 is provided with the handle 7 5 secured thereto in any suitable manner, as, for example, by the pin 76, and its other end projects through the opposite side of the box and is provided with a collar 77 rmly secured thereto in any convenient manner, as by the set screw 78. Upon the rod 65 is the hub 8O which is provided with a screw threaded aperture, the screw threads engaging with the screw threads on the rod 65, and this hub is provided with the two projecting arms 81 and 82, through the projected ends of which the rod (50 is passed, and between which is located the pulley 61. Secured to the hubs of the arms 63 and Gd, and extending` parallel with said rod 65, but spaced therefrom suiiiciently to admit the hub therebetween, are the two bars 83 and l84 which connect said hubs rigidly each with the other. he operation of this part of the apparatus is as follows: By turning` the am nut 68 by its handle 69, the hub otl the arm G3 is 'freed so that the arms G8 and (Set may be raised or lowered by means of the handle 70. As these arms are raised or lowered,the rod 60 is also raised or lowered together with the arms 81 and 82 ot the hub 80, and it" the parts are in the position shown by `Fig. 2 of the drawings, raising of the pulley 61 will relieve the tension on the belt 5st and then, by operating the handle T5, the hub SO will be moved to the right or left, see Fig. 4, and in its movement will shift the pulley G1 and the belt 54. When the belt has been shifted to its new position, the pulley 61 may be 'forced down upon the belt to tighten it by manipulating the handle TO, and can be retained in such position by the jam nut (35, as will be readily apparent.

lCneircling two o1 the pipes 1li, are clamps to which are secured pitinen rods )1 which are also secured one to crank arm 92 and the other to bell crank lever 921 both secured. to a length ot pipe or tube El?) which incloses one oit the lengthwise brace rods 3. The bell crank lever 921 is connected with the pitinan rod 9i, which in turn is connected with the strap of an eccentric 95, which eccentric is secured to the countershaift ett).

it will be apparent that when the shaiit l() is rotating, the bell crank lever and the pipe shattwill be oscillated and by means o1 the crank arm J2 and bell crank lever 021 and pitinan 91, the table as ay whole will be swung upon the supports 5.

For clearncss et illustration, some bracing rods which are ordinarily extended between the standards, are not shown, as well as the greater part oi3 the ore it'eeding and water supplying apl aratus.

rihe numeral designates a water pipe for supplying water to the adjustable launder 101, which may be supplied with a plurality ot distributing pipes 102, as clearly shown by Figs. 1 and 2.

The numeral 103 designates the customary ore distributing tray.

The belt 30 is given a continuous traveling movement from the belt wheel 45, through the shaft- Ll0, the cone pulley 118, belt et, cone pulley 9, shaft 50 and spiral gear 53, which in turn meshes with the spiral gear Q00 secured upon the shaft 201, said shatt being composed of the sections 209, Q03 and 20a, the section 202 carrying the spiral gear 200 and having' an enlarged portion 205 which abuts against its bearing in the box d2, the section 20dbeing provided with a worm 20G, the intermediate section 202i being `united by universal couplings with the menibers 202 and 20a. rPhe worm Q06 meshes with the gear 20T, which is fast on the shaft 20S of the roll 1G. The numeral Q09 designates a easing which incloses this worm and worm gear to protect them from water and dust, while the spiral gear Q00 is protected by being placed within the box 12.

rlhe operation of machines olf this general type is so well known, and they have been in use so many years, thaty it is not considered necessary to explain in detail the operation o'f this specific machine except to point out that in the operation of the machine the belt can be inclined more or less by means ot the turnbuckles 5, and the inclination ot the turnbuekles from the vertical` may be adjusted more or less by means of the screws 11.

Ot course it is to be understood that the ordinary ore receiving tanks, launders, and similar accessories are intended to be used with this specific machine in the same way that they are used with machines of a simi lar kind at present in use.

By placing the countershaft 40 across the machine as shown, it is possible to place batteries of the machines parallel witha line shaft and drive them with straight belts.

It will be noticed that the parts of the machine are so disposed that the working parts are high up out of the way of the water and that all parts are thoroughly protected.

What is claimed and desired to secure by Letters Patent is:

l. The combination in a vanner, of supports, a belt frame suspended from said supports, an endless belt supported by said belt frame, a countershaft mounted on said supports and extending transversely of the vanner with respect to the length of the belt, means for driving said belt from said countershaft, a pipe shaft extending longitudinally of the vanner with respect to the vlength of the belt, a rod connecting two of said supports and carrying said pipe shaft,

a bell crank lever xed to said pipe shaft, an arm fixed to said pipe shaft, pitmen rods connecting the bell crank lever and the arm respectively to the belt frame near respective ends thereof, an eccentric on the countershaft, an eccentric strap, and a pitman rod connecting the strap and bell crank lever.

2. The combination in a vanner of four supports, a pair of brace rods connecting two of said supports at each end of the machine, said brace rods being spaced apart, blocks supported by said brace rods, turnbuckles extending between said brace rods and depending from said blocks, a concentrating table secured to said turnbuckles, and screw means for adjusting the position of said blocks on said brace rods.

In testimony whereof, I aliix my signature in the presence of two witnesses.
